In the 26 years since the first offshore wind farm was installed in Vindeby, Denmark, the offshore wind industry has undergone remarkable growth. Recently, this growth has accelerated, advancing farms rapidly into deeper water and utilizing larger turbines. As offshore wind farm developers continue to look towards heavier, higher capacity...

With changes in weather patterns and intensifying anthropogenic water use, there is an increasing need for spatio-temporal information on water fluxes and stocks in river basins. The assortment of satellite-derived open-access information sources on rainfall (P) and land use/land cover (LULC) is currently being expanded with the application of...

In this research, three faecal sludge sanitizing methods—lactic acid fermentation, urea treatment and lime treatment—were studied for application in emergency situations. These methods were investigated by undertaking small scale field trials with pit latrine sludge in Blantyre, Malawi. Hydrated lime was able to reduce the E. coli count in the...

We present a case study of the 5 April 2010 geomagnetic storm using observations and numerical simulations. The event was driven by a fast-moving coronal mass ejection and despite being a moderate storm with a minimum Dst near ?50 nT, the event exhibited elevated thermospheric density and surges of traveling atmospheric disturbances (TADs) more...

Flooding resulting from hurricanes and other extreme storm events is a prominent risk along the coasts. These coastal areas are typically of low elevation and relief,making land and infrastructure highly susceptible to inundation by storm surge and waves. These verity of this threat is exacerbated by sea level rise and a possible increase in...

Vertical faults through the shallow crust are commonly believed to act as either barriers to horizontal groundwater flow normal to the fault, conduits to horizontal flow tangential to the fault, or a combination of both. In addition, enhanced vertical permeability has been identified as a common feature. We investigate the effects of vertical...

The electrical resistivity measured by well logging tools is one of the most important rock parameters for indicating the amount of hydrocarbons present in a reservoir. The main interpretation challenge is to invert the measured data, solving for the true resistivity values in each zone of a reservoir. Inversion is not always an easy task...

The objective of NCHRP Project 15-2 has been to establish criteria and develop procedures for the design of armored channels. The first phase of the project resulted in NCHRP Report 108, "Tentative Design Procedure for Riprap-Lined Channels" (1), which describes procedures for designing such channels and proportioning the riprap so as to...
